The object of this invention is to obtain a machine which shall be simple in construction,'not liable to get out of order, not liable :5 to break, bavingfew parts or pieces, and not containing any small separable parts or piecee' 'tliaiv is, parts or nieces which can eaeily be removed from the maol 1lne-and to obie-in a machine easily and accnratelyadjust- 1 'ed to correspond with the size of the rice or other like material which is being operated on thereby, as well as to correspond with the kind or character of the work to be done trier-eon, whether the same be simply boiling the rice or other material or cracking or breaking the SEi-ll19-' 4 o I In the drawings referred to as forming a part of thie'epecification, Figure l is a vertical sectional. iow of the operative parts of gobb e machine on line, 1 1 of 2, viewed in the direction. indicated by the arrow;'and

It all be observed that by makingthe jourual-bearin s D D in one piece, as described, loosening of the bolts D, D, by which such bearings are attached to frame A, would not permit the separation from theshaft G of such bearings so long as the cranks F F remained secured to the shaft, although such shaft, the cranks, collars, and journal-bearings could then be removed from the frame of the m acliine. ratuo is especially fitted for use in localities where opportunities for obtaining or manufacturing such small parts are not present, as there is but little liability of separation or ore of any of such parts n n a shaft rotataolymounledirrjournalh is a spirally-extondin g rib on shaft I-I, ro-

Shaft H e2t- O is ornament or concrete disk rigidlysocured on the face of the frame, wheel, or disk N, the meeting faces thereof and the disk having coresponding ribs and recesses in the same manner as have the meeting faces of the wheel L and disk M hereinbefore described.

P is the hopper of the machine.

In order to make the grinding-disks Maud 0 adjustable relative to each; other, I mount disk 0 immovably, as stated, and I construct the journal-bearing I so that the shaft II is longitudinally, as well as rotatahly, movable therein and the jouruatbearing J so that the longitudinal movement: of the shaft H is de i termined and controlled thereby. -.For this purpose the journal-bearing .I comprises the following-named parts: immovable part q, movable part 1', ar lockingnnts s s. The movable part a is on qneoutside thereof provided with scretv-th reads t i, fitting into corresponding internal screwthreads in the nuts 8 s, respectively.

u is a feather or spline engagingwith iinmovable part q and the movable part i to permit longitudinal movement of the part 1'. and preventing rotation thereof. 'lhe'shai't H is rotatable in the movable part 7".

When constructed as above described, if the out 3 on/cne end of movable part 7' he loosened and the nut on the other end of such movable part r be correspondingly tightened the longitudii'ially-movahle part fr will thereby be moved longitudinally, and the ends of the movable p rt 7" coming in contact, respectivelypvi'th the ends of the hu be of Wheels K and L, which are respectively adjacent thereto, the shaft H and all theparts attached thereto, including wheels L and. disk M, are I moved longitt1dii1ally,thns moving disk M v to or away from? the disk 0, thus obtaining adjustment of such disks relative to each other. A very close adjustment of grinding-- disks M and O is thus obtainable, and the adjustment obtained is accurately maintained. The operation of the machine is: Rice beceases.

By properly adjusting the griuding-disksjs M and 0 relative to each hereinbefore described the be broken when desired. It is evident that other may be put through this machine, as seeds of various kinds, either for the purposeiof' hulling 'the same or of breaking them up. Having thus described the machine em bodying my invention and the manner of.,0perationthereof, what I claim as new, and tie sire to secure by Letters Pateut,-is- The com bination of a longitudinally and rotatably movable shaft, a grinding-disk immovably mounted on the frame on which the other in the manner grains of rice may material than rice shaft is mounted, and having an axial apertore; means for rotating the shaft, and means for moving it longitudinally, the latter comprising a journal-bearing consisting of an immovable part secured to the frame, a lon gitudinally'movable and non-rotatable part in the immovable part and extcnd'ingbeyond the sides thereof, such movable part having external screw-til reads and nuts on'the screw threads arranged to be turned against. the

sides of the immovable part, a disk rigidly I secured on the rotatable shaft and means for depositingmaterial between the disks through the axial aperture in the immovabledisk;

substantially as described.
